Abstract

A method is described to provide shock and electrical isolation between a small hard disk drive and a using system box. This invention occupies much less space around the periphery of a disk drive than a conventional user frame, thereby allowing the exterior walls of a drive to extend outwardly to within a fraction of a millimeter of the standard form factor dimensions and hence provides more volume within the file enclosure.

Abbreviated User Frame for Small Disk Drives

      A method is described to provide shock and electrical isolation
between a small hard disk drive and a using system box.  This
invention occupies much less space around the periphery of a disk
drive than a conventional user frame, thereby allowing the exterior
walls of a drive to extend outwardly to within a fraction of a
millimeter of the standard form factor dimensions and hence provides
more volume within the file enclosure.

      Fig. 1 shows a 2 1/2-inch disk drive 1 with the electronics
largely packaged on a single printed circuit card fitted to the
bottom side of the drive.  The sides of the drive extend downward
beyond the bottom of the enclosure skirt around the electronics card.
Openings are provided in the skirt to expose the circuit card edge
connector 2 and to accept the two abbreviated user frames 3 (one each
side).  These members may be die cast as illustrated or may be
stamped and formed.  Resilient, energy absorbing pads 4 are attached
near each end of each abbreviated frame member 3 and, when installed
to the drive, are bonded to the inside of the overhanging skirt.
Sufficient clearance is provided between each abbreviated frame
member 3 and the skirt openings so that small relative motions can be
accommodated, and also the frame members 3 extended slightly beyond
the drive periphery to assure contact will not occur between the
drive enclosure 1 and the system box.  Side and bottom mounting ho...
